Operations on Functions

The Dylan language defines a number of functions which operate on other functions.

There are two broad categories of these functions:

Introspective functions take a function as an argument and return information about it. These are described in "Reflective Operations on Functions" on page 338.
Higher order functions take one or more functions as arguments, and return a new function. These are described in "Functional Operations" on page 332.
